If only they wore sunglasses

The Q&A section of your June issue mentioned a study in the Czech Republic and Germany (p82) that reported that dogs tend to poo aligning themselves with the north-south axis of the Earth’s magnetic field. I have my own theory. They poo facing north to avoid having the Sun in their eyes while going about their business and because they feel safer being able to see any approaching predators, from at least one direction anyway. If researchers in the southern hemisphere had the time to do a similar study, I suspect they might find dogs aligned themselves with the Earth’s magnetic field but facing south.
